I just added tethering to my Verizon account and I downloaded VZAccess Manager and installed it. When I go to run it I can get up to the screen that displays "Adding modem." It lists what I'll have to perform over the next couple steps of the wizard but once I hit "next" the button greys out and it just sits there and doesn't do a thing.'
It says it's going to go into the control panel and add a modem under "phones and modems." So I tried to do it myself manually but it doesn't have the same options that the wizard says there should be.
